Pepton^®

Our additives and ingredients enhance manufacturing processes and the performance of products.

Thomas Swan has developed a range of viscosity-reduction additives for the rubber processing and polymer industries, providing time, energy, cost and environmental benefits. Pepton^® chemical peptisers catalyse the mastication of rubber, providing time, energy, cost and environmental benefits.

The dibenzamido diphenyl disulphide (DBD) chemistry used to produce the active ingredient within Pepton^® is widely considered by the rubber processing industry to be more environmentally acceptable than traditional pentachloro thiophenol based peptisers. Thomas Swan’s DBD is the only fully REACH registered chemical peptiser.

A range of formulated Pepton^® products is available, each having different concentrations of the active ingredient combined with a range of complementary proprietary additives that enhance peptising performance.
